Our 6063 aluminum sunflower heat sink is a high-performance cooling component produced from extruded aluminum profile. After extrusion forming, we adopt precise CNC milling process to complete hole drilling, square slot machining and contour trimming, followed by full deburring treatment. The surface retains natural brushed aluminum finish without anodizing.

As a reliable heatsink manufacturer, we support custom & OEM service to modify dimensions, fin quantity, hole layout and surface treatments according to clients’ drawings or samples. This sunflower-style aluminum cooling heatsink delivers efficient heat dissipation for compact equipment and small motors, meeting strict dimensional tolerance requirements for assembly.

• Small DC / AC motor thermal dissipation
• Drive controller cooling
• Electronic power module heat dissipation
• Sensor and compact electrical equipment cooling
• Household electrical drive assemblies
• Automation equipment miniature power unit
